binomial_authority ="Songlingornis" is a prehistoric
bird genus from the EarlyCretaceous . Itsfossil s have been found in theJiufotang Formation ofLiaoning (PRC ). The age of these rocks is somewhat disputed, but probably around the earlyAptian , 125-120 million years ago. Only onespecies , "Songlingornis linghensis", is known at present.It was a close relative of "
Yanornis " and together with this and "Yixianornis " forms aclade of early modern birds [Mortimer (2004), Clarke "et al." (2006)] . It is sometimes considered to be the same genus as "Yanornis" (which, described after "Songlingornis", would then be merged into thattaxon ) [Gong "et al." (2004)] , but this is not universally accepted [Mortimer (2004)] .Footnotes
